It also requires giving a very close look at the mechanical requirements of building the drive system of your bot. It’s all too easy to go overboard and plan a drive system that’s too
complex or expensive to build. In this article, I’ll review the three
main locomotion systems for desktop robots, and things to keep
in mind when deciding which one is right for your next
mechanical creation.

Using Wheels

Wheels are the most common way to move a bot. For
wheeled robots, their drive geometry is defined by how each
one is steered. There are a lot of choices. The most common
way to move a robot is with differential steering.

The most basic form consists of two wheels mounted on

All mobile robots move. That's what makes
them mobile, after all. Wheels, tracks, and
legs are the most common ways to propel a
robot across the floor. Which one should you
use? That can be a tough question. Selecting
the right system starts with figuring out
what you want your robot to do.
